NSMutableArray addObject not adding objects, and object IS allocated?

The TT_RELEASE_SAFELY macro sends a release message to its argument before assigning it to nil (IIRC). Why is it any surprise that _positions is nil?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
